What's in a (CentOS) version number?

The comments on SL are very interesting. I knew, of course, that it was well maintained by Fermi labs and CERN. They are hard working enough that they will maintain backports of all security fixes for each point release and also maintain archives of all point releases.

I knew also that there was discussion about SL becoming a CentOS SIG. That would be good and useful so long as it doesn't impact the level of support SL currently provide.

The rationale behind starting SL does make sense - I can't see anyone paying for 10,000+ servers and the servers needed to run an additional PB of storage each and every month for the LHC :)
